Embodiment 1

[0048] In the first step, 30 parts by weight, smash, 40 mesh sieve, spare.

[0049] In the second step, 50 parts by weight of superfine mine particles having a particle diameter of 500 microns were added to the first step product, and 2 parts by weight of humic acid, 2 parts by weight of humic acid. 15 parts by weight of the biochemically treated animal feces, mixed fermentation of 100 min, reaction temperature is 40 ° C,

[0050] In the third step, 3 parts by weight of the chemically treated seaweed is added to the second step product, and after stirring mix, the material is sent to the disc granulator for granulation, and the granulated particles finally enter the drum dryer. Drying under temperature conditions at 80 ° C, while the material was frictionally friction in the drying cylinder for secondary granulation.

[0051] In the fourth step, the dry particles are fed into the cooler for cooling, sieving, inspection, metering, packaging, product compound fertilizers.

Embodiment 2

[0053] In the first step, 50 parts by weight, crush, 40 mesh sieve, spare.

[0054] In the second step, 40 parts by weight of the micro-ineralizing substance obtained by coal and coal gangue microallite separation techniques were added to the first step product, 3 parts by weight of yellow rot acid, 3 parts by weight of yellow rot acid, seaweed 7 parts by weight of the activation liquid, staying for 100 min in the fermentator, fermentation temperature 35 ° C.

[0055] In the third step, stir the first product and the second step product, after mixing, the material is sent to the disc granulator for granulation, and the granulated particles finally enter the drum dryer under 80 ° C temperature conditions. Dry, while the material is frictionally rubbed with a dry cylinder.

[0056] In the fourth step, the dry particles are fed into the cooler for cooling, sieving, inspection, metering, packaging, product compound fertilizers.

Embodiment 3

[0058] The first step is to take 35 parts by weight, smash, 40 mesh sieve, spare.

[0059] In the second step, 60 parts by weight of the superfine mine particles having a medium-micrometer particle obtained in the first step of the micrometer separation technique were added to the micrite separation technique, and 3 parts by weight of the organic chelating agent EDTA were mixed. 200min, making it chemically chelated reaction.

[0060] In the third step, the first step product and the second step product are stirred, and 2 parts by weight of the black rot is mixed. After mixing, the granulation is added to the disc granulator, and the granular particles are finally entered into the roller bake. The dryer dried under temperature conditions at 80 ° C while the material was frictionally fed twice with a dry cylinder.

[0061] In the fourth step, the dry particles are fed into the cooler for cooling, sieving, inspection, metering, packaging, product compound fertilizers.

Abstract

The invention discloses a compound fertilizer rich in minerals, which comprises the following raw materials in weight percentage: A, mineral particles separated from coal or coal gangue before combustion or chemical transformation, 10-80%; B, organic Chelating agent, 0-10%; C, biochemically treated animal manure / algae raw material, 5-40%; and, optionally D, at least one of nitrogen fertilizer, phosphorus fertilizer, and potassium fertilizer; 5-50%. The mineral particles in the present invention are rich in at least one of medium and trace elements necessary for plant growth such as B, Ca, Cl, Cu, Fe, Mg, Mn, Mo, S and Zn. The invention can realize the most economical and efficient utilization of the mineral waste in the coal chemical industry. The invention also discloses a preparation method of the mineral-rich compound fertilizer.

Description

Technical field [0001] The present invention belongs to the fertilizer industry, and specifically involves a compound fertilizer rich in mineral substances and its production processes. Background technique [0002] Fertilizer is the food of crops, my country is one of the largest countries with the largest fertilizer, accounting for 8% of the world's cultivated land, but uses about 30% of chemical fertilizers, due to excessive or unreasonable fertilization, resulting in a decline in output, increased Cost of production. In addition, excessive use of fertilizers also brings a series of issues: [0003] (1) Soil strip [0004] Long-term single application of fertilizers, resulting in acidification soil, bacteria in the soil are killed, and humicity cannot be added in time, which will cause soil strip. After the excessive displacement of the soil, the nitrogen supply of the microorganism increases by 1, and the corresponding carbon is increased by 25, the carbon consumed is derived...
